Eureka!)))

How it works?

Nice train)) Chuuu chuuu =)

thx

cool train, bro xD

Thanks for the help friend, made it clear =)

That test checks if the functions are independant. It defines more than one lazy function, then calls them at intervals to make sure that each one is only affecting itself.

Example (not the real test):

@lazy(3)
def a():
    pass
  
@lazy(-2)
def b():
    pass
  
a() # Works
b() # Works
b() # Lazy
a() # Works
b() # Works

Functions a and b should each be on their own independant 'timers'.

My solution passed all tests (Passed: 307 / Failed: 4), except for the "Multiple lazy functions should work fine" block. Please tell me how it should look like?

:D
